There is still no clear evidence as to how the Qbot virus entered the Melbourne Health network and disrupted some of Royal Melbourne Hospital's systems, but it appears to be able to infect PCs running any version of Windows, the organisation says.
The worm first attacked Royal Melbourne a fortnight ago, forcing the hospital to temporarily abandon some of its clinical systems and institute manual work-arounds, particularly in pathology. Pulse+IT understands this is the second virus to bring down the pathology department in the last six months.
As Pulse+IT revealed last week, the culprit turned out to have been a Qbot or Qakbot worm, which is known to affect older Windows operating systems, in particular XP.
